MOLD CHILL.

Application tiled January` 31, 1927.

My invention relates to a mold for founding' metal and it has particular' reference to a chill for manufacturing liners for ball and rod mills, the objects of the invention being to provide a simple and inexpensive mold which will eliminate all skilled labor and save all material now neededand required in making sand molds, thereby reducing the cost ot production of casted articles and ett'ecting a considerable economy in time.

Another object of the invention is to provide a permanent mold by which the articles or bodies founded will be uniform in weight and free from any of the imperfections usually'encountered in casting articles in sand molds.

rThe accompanying drawing illustrates a preferred form of embodimentof my invention and therein Fig. 1 is a plan view. Fig. 2 is a sectional elevation, the section being taken on line 2 2 Fig. 1. Fig. 3 is a section taken on line 3 3 Fig. 1, looking in the direction of the arrow. Figure 4 isa plan view of a modified form, and Fig. 5 is a sectional view on line 5-5 Fig. 4t. Similar reference characters on the drawing denote 'similar parts. Referring particularly to the form of the embodiment of the invention which is shown in the drawing, my improved mold comprises generally two sections 1 and 2 formed for mutual co-operation to produce the design, shape or outline desired of founded articles or bodies, suitable means being provided to convey the melted metal into the mold formed by sections 1 and 2.

'l1 he section 1, which is the base or bottom of the mold, is substantially rectangular and is preferably provided with longitudinal and transverse members 3 and t respectively, which support the base 1; but it will be obvious that these supporting members 3 and etA may be omitted. The section 1 is provided with front and rear upstanding walls 5 and 6 respectively, and the sides of same are open. 'The upper face 1a of the section 1 constitutesv the bottom of the mold imprint, which as shown in Figs. 3 and 5 is narrower and shorter than the base section 1, providing thereby lateral plane ksurfaces 6 and a front plane surface 7, for purposes now explained. The section 2 or top section is arranged for movement relative lto the section 1, and for this purpose may be hingedly connected to the rear upstanding wall tj of the section l, This section is pre1 Serial No. 164,77*?.

vided with downwardly extending side walls 8 which, when the section 2 is closed upon the sect-ion 1, rest upon the plane surfaces (5 which adjoin the imprint face 1 of the bottom section 1. rlhc front and rear of said section 2 are open, as shown in Figs. 2 and 5 the rear of said section 2 in the form shown in Figs. 1, 2 and 3 being arranged to be closed by the rear upstanding wall 6 of the section 1, when the sections are in operative or closed position; and the front of said section 2 being arranged to be closed by a plate 9. This plate 9 is held in place against the front open end of the section 2 by wedge members 10, which are arranged to be inserted between projections 11, pro` vided on said plate 9, and the front upstanding wall 5 of the section 1. The plat-e 9 is also provided intermediate the ends thereof with spaced. outwardly directed lugs 12, between which is arranged to Ibe set and removably heldin place by wedges 13, a` gate 14, the bottom of which is arranged to extend through an opening 9 in the bottom of and preferably centrally of the plate 9. The gate 14 is provided with a sprue 11i, and may be made either solid and of metal, sand or any other suitable material, or may be composed of sectionsas shown `in 1 and 3.

Vllhe section 2 as shown in Fig'. 3 is formed to produce the shape, outline or design of the upper part of the founded product, and is provided with a tapering opening' 15 which penetrates the top thereof for a core 16 of metal or sand to form in the finished casting an aperture for the accommodation of a bolt, screw or other device by which the product founded in the mold may be attached.

ln the form of the invention illustrated in Figs. 4t and 5, where no hinged connection is provided between the top and the bottom sections 1 and 2 respectively, the open front and rear of the section 2 is arranged to be closed by removable plates 9, which are adapted to be held against the respective open ends of the section 2 by wedge mem` bers 10. These wedge members are arranged to be inserted between projections 11, provided on the outside of the plates 9, and the upstanding walls 5 of the sections 1. Each of the closure plates 9 is provided with spaced outwardly directed lugs 12, and between these lugs 12 are arranged to be set and held place by wedges 13, gates 14, the

bottom of each of which is arranged to extend through an opening 9 provided in each of the plates 9 at the bottom and preferably centrally thereof. Each of the gates 1% is provided with a sprue lit', and may be composed of sections. as shown. or ma)v be made solid and of any material desired. The latter arrangement of mold as described is very desirable for heavy work.

lVhat I claim, is:

l. A mold comprisingr a base section hav ing front and rear valls, a top .section connected with said base section at one end thereof, and arranged for movement relative thereto. said top section being open at its respective ends and provided with downwardly extending side walls which are arranged to rest'y upon Said base section and between the upstandingr walls thereof, the rear upstanding wall ot' said base section arranged to close the rear opening` of said top section. a removable closure for the front of said top section. means to hold said closure in position. and a removable gate having the bottom thereof extending through said closure.

2. A mold comprising a base having upstanding front and rear walls, a section hingedly connected at one end to said base and being of less longitudinal extent than said base, said section being open at its respective ends and having side walls arranged to rest upon said base and between the front and rear walls thereof. a closure for the front of said hinged section, means to secure said closure in position, a gate havingr the bottom thereof extending tarough said closure, and means to .secure said gate in position on said closure.

3. A mold comprising; a base having upstandingr front and rear alls. co-operating` mold section hingedlv connected to said base, said section having open ends. one of which is arranged to be closed by the rear upstandingl wall of said base, a removable closure for the other end of said rection. nuans to secure said closure in position. :ind a .frate removabl)v fastened to said closure.

4. A mold comprisingr a base having upstandine' front and rear walls. a .section cooperating with said base and connected therewith for relative nioveinent. .said .fertion beine open at; its ends and arranged to lit between said upstanding' walls wherebj.v the rear open end of said section is closed h v the rear wall of said base, a removal le closure for the front open end of said fection. said closure l aving a pluralitv of projectingr lugs intermediate the ends thereof. a gate between .said lug.` and having the bottoni thereof extendingr through .said closure, and means to secure said gate in poffition.

It mold comprisingtwo sections hingedlv connected. one of said sections having front and rear walls and the other ,section having side walls arranged to rest upon .said lirst named section and to engage the rear wall thereof, a closure for the front end of said other section. a gate having its lower end evtemlingr through said :los-ure. and means to removably connect .said gate with said closure.

A mold comprisingI a plurality ol seetions hingedl)v united for relative movement. the front of one of said sections beineopen. a ren'iovahle closure for said open front. means engaging one of said section-fy and said closure to hold said closure in position. and a gate re1novabl7 connected with and extending through said closure.

7. It mold comprisingr a base section having front and rear walls. a top section open at its respective ends and provided with downwardhv extending side walls arranntal to rest upon said base section. an end closure for said top section. and a grate associated with said closure.

ln testimonvIv whereof l have set in v hand.
